Abstract
A new hierarchical mean-residual image vector quantiser (HMRIVQ) using a general 4-dimensional gradient-Laplacian subspace distortion (GLSD) is proposed. With the use of the GLSD the computational and storage costs of the encoder are significantly reduced. The HMRIVQ can also achieve a very high compression rate for low detailed images.
